25. Check Installation and Start-Up
Check the installation prior to start-up: 5. Thermostat calls for heat, energizing the venter motor.
6. Venter pressure switch closes, firing the unit, after pilot prov-
ing sequence.
7. Fan control senses heat exchanger temperature, energizing
the fan or blower motor.
8. If the flame is extinguished during the main burner operation,
the safety switch closes the main valve and recycles the spark
gap.
On units equipped with lockout device, if the pilot is not
established within 120 seconds, the unit locks out and must
be reset by interrupting power to the control circuit. (See
lighting instructions on the heater.)
Check installation after start-up:
† With the unit in operation, measure manifold gas pressure.
See Paragraph 11.
† Turn the unit off and on, pausing two minutes between each
cycle. Observe for smooth ignition.
† Blower Model - Check motor amps with an amp meter. The
maximum amp rating on the motor nameplate must not be
exceeded.
† Place 'Owner's Envelope" containing Limited Warranty Card,
this booklet, and any optional information in an accessible
location near the heater. Follow the instructions on the enve-
lope.
† Check suspension. Unit must be secure and level.
† Blower Model - Check to be sure that all shipping supports
have been removed. Rubber feet must be on the motor bracket
bolts. See Paragraph 3.
† Check clearances from combustibles. Requirements are shown
in Paragraph 7.
† Check vent system to be sure that it is installed according to
the instructions in Paragraph 10.
† Check piping for leaks and proper gas line pressure. Bleed
gas lines of trapped air. See paragraph 11.
† Check electrical wiring. Be sure all wire gauges are as recom-
mended. A service disconnect switch should be used. Verify
that fusing or circuit breakers are adequate for the load use.
† Check that any field-installed options have been included in
the installation.
† Blower Model - Check belt tension. See Paragraph 15.
Start-Up -- Typical Operating Sequence:
1. Set thermostat at lowest setting.
2. Turn on main and pilot manual gas valves.
3. Turn on the power to the unit.
4. Set the thermostat to desired setting.
DANGER: The gas burner in this gas-fired equipment is designed and equipped to provide safe and
economically controlled complete combustion. However, if the installation does not permit the burner to
receive the proper supply of combustion air, complete combustion may not occur. The result is incomplete
combustion which produces carbon monoxide, a poisonous gas that can cause death. Safe operation of
indirect-fired gas burning equipment requires a properly operating vent system which vents all flue products
to the outside atmosphere. FAILURE TO PROVIDE PROPER VENTING WILL RESULT IN A HEALTH
HAZARD WHICH COULD CAUSE SERIOUS PERSONAL INJURY OR DEATH.
Always comply with the combustion air requirements in the installation codes and in Paragraphs 7 and 8.
Combustion air at the burner should be regulated only by manufacturer-provided equipment. NEVER
RESTRICT OR OTHERWISE ALTER THE SUPPLY OF COMBUSTION AIR TO ANY HEATER. Indoor
units installed in a confined space must be supplied with air for combustion as required by Code and in
Paragraph 8 of this heater installation manual. MAINTAIN THE VENT SYSTEM IN STRUCTURALLY
SOUND AND PROPERLY OPERATING CONDITION.
